🤖 fix: de-flake integration tests

- resumeStream.test.ts: Remove brittle assertion checking for specific text
  content. Now validates the response has parts (text, reasoning, or tools)
  instead of requiring exact text output.

- helpers.ts: Increase timeout constants to handle slower CI environments:
  - STREAM_TIMEOUT_LOCAL_MS: 15s → 20s
  - TEST_TIMEOUT_LOCAL_MS: 25s → 50s (supports 2+ LLM calls per test)
  - STREAM_TIMEOUT_SSH_MS: 25s → 35s
  - TEST_TIMEOUT_SSH_MS: 60s → 90s
